摘　　要：在剪切增稠胶(shear thickening gel,STG)中掺杂一定量的涤纶短绒,借助电子单纤维强力仪和动态机械分析仪分别对涤纶的强伸性能和掺杂不同长度涤纶短绒后的STG的动态力学性能进行测试。结果表明,具有一定强力的涤纶短绒能够提高STG的动态力学性能,发挥增韧的作用,且在低频率剪切下长度大的涤纶短绒增韧效果好,高频率下则相反。A proper number of polyester(PET)flocks was doped in shear thickening gel(STG).The strength and elongation properties of PET filaments were measured by electronic single fiber strength tester,and dynamic mechanical properties of STG doped with different lengths of PET flocks were tested via dynamic mechanical analyzer.Results show that PET flocks with proper strength can improve the dynamic mechanical properties of STG and perform a toughening effect,and longer flocks under low shear frequency enhance the effects,but that with high shear frequency oppositely decrease the effect.
